LASTING-PINCHERS.

SPECIFICATION forming part of Letters Patent No. 418,762, dated January 7, 1890.

Application lcd October 11, 1889. Serial No. 326,668. (No model.) i

To all whom it may concern:

Be it known that I, ANDREW SIEGEL, 10 lI-Iyde Park, in the county of Norfolk, State "of Massachusetts, have invented certain new and useful Improvementsin'Lasti-ng-Pinchers, of Which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specication, in Which- Figure l is a side elevation of my improve pinchers; Fig. 2, an edge elevation looking from the left in'Fig. 1, the handles being shown broken off; Fig. 3, a transverse sec- Ation taken on line a: in Fig. l; Fig. 4, an

enlarged elevation of thevhammer removed; Fig. 5, an elevation of the pincher-jaws with the hammer detached; and Figs. 6, 7, and 8, detail views of the clamping-nut. j

Likev letters of reference indicate corresponding parts in the diierent figures of the drawings.

My invention relates to that class of pinchers employed, especially, in lasting boots or shoes; and it consists in certain novel Vfeatures hereinafter fully set forth and claimed, the object being to produce asimpler, cheaper, and more effective `device of this character than is now in ordinary use.

The nature and operation of the improvement Will be readily understood by all conversant with such matters from the following explanation:

In the drawings,A B represent the handles, which are respectively provided with curved jaws b d, and pivoted together at f, in the usual manner. The jaw d is enlarged or thickened at g, said thickened portionbeing provided With a longitudinally-'aman ged dovetail groove 72.. Anutt' is fitted to slide in said groove, said nut having two fiattened parallel edges j, which prevent it frombeing rotated therein. A hammer D has a central spindle k, adapted to project into said groove and be turned into the nut, the body portion e of the hammer bearing against the Walls of the groove when in position. An opening m is formed in the head p of the hammer to receive a tool whereby it may be rotated.

It is well known that the widths of boots or lasting a shoe-upper, the hammer bears against the shank, and when said Shanks are narrow the hammer frequently slips thereon. In my improvement by turningthe hammerspindle la partially out from the nut/said nut may be made to .slide in the groove and the hammer adjusted at any desired distance from the end of the jaw d. By turning the spindle into the nut again it is drawn tightly against the Walls of the groove and clamps the hammer D firmly in position in a manner which will be readily understood Without a more explicit description.

Having thus explained my invention, what I claim is- 1. In lasting-pinchers, a groove in the under jaw, a nut 'fitted to slide therein, and a hammer having a threaded spindle adapted to Work in said nut andclamp said hammer in position on said jaw, substantially vas described.

2. Lasting-pinchers comprising the pivoted handles A B, provided with jaws b d and groove h, the nut t' itted to slide in said groove, andthe hammer D, provided with the threaded spindle k for receiving said nut, substantially as and for the purpose set forth.
